VENTILATING SUBWAYS.

Specicaton o'f Letters, Patent.

Patented April 9, 190'?.

Application iiled May 1,1906. Serial No. 314,679.

To (LZZ whom it may concern.-

Be it known that I, THEODORE D. ROBIN- soN, a citizen of the UnitedStates, residing at Albany, in the county of Albany and State of NewYork, have invented a new and useful Improvement in Ventilating Subways,of which the following is a speciiication, reference being had to theaccompanying drawings, forming part thereof.

The object of my invention is to provide a new and improved means Jfordisposing of the vitiated atmosphere and gases in a subway, that isentirely hidden from sight and discharges its vitiated contents at thehighest point possible without erecting unsightly means for sodischarging it.

Figure 1 shows a longitudinal sectional view of the ordinaryentrance-way from the street to a subway, showing the kiosk and housingof the entrance excavation and my means or invention shown in a similarsectional view. Fig. 2 shows a longitudinal sectional view of one of myrevoluble transparent shutters; Fig. 3, a vertical sectional view of oneend of the housing, taken on line a a. of Fig. 1; Fig. 4, a verticalsectional view of a subway and kiosk, with my invention shown partly inside elevation and partly in vertical section; and Fig. 5, a verticalsectional view of another form of my invention.

The numeral 1 shows the kiosk, and 2 the housing over the entrance, theroof of the housing and sides of the kiosk being of transparentmaterial, as glass, so that the entrance may be more or less lighted bythe daylight.

At 7 is seen a ceiling which in part covers the entrance-space, butleaves a considerable space between it and one side of the kiosk,leaving an entrance to the open-sided chamber 10. From this opening andin operative connection therewith drops the conduit 6 and passeslongitudinally underneath the roof of the housing and drops again at therear end of the housing and passes into the subway forming thepassage-way 3', thus forming a conduit which receives the foul air andgases in the subway directly under its crown or arch and bynatural draftcarries them away, emptying them in the open chamber 10, whence theyescape to the atmosphere. This` conduit 6 is preferably made oftransparent material and has pivoted portions, as seen at 6 in Figs. 1and 2, which swing so they may be opened and closed at pleasure, so theymay readily be cleaned and then shut again, forming a closed conduit inthat portion at least whichreceives the light of the sun, and thus itslight is made use of in lighting the entrance-way, kiosk, and housing.That portion of the conduit that lies under the arched roof of thesubway has a damper 62 to shut off the action of the draft wheneverdesired and also has a trap-door dropping downward, as seen at 63, theobject being that if a train is passing in the direction of the arrow tthe hanging door 63 will direct the forward-moving air into the conduit6 with more or less force and assist the natural draft already in theconduit, the damper 6z being open. 3 denotes the rear transparent end ofthe kiosk, 4 the sidewalk, and 9 the earth or ground, and 8 the stairsto the entrance-way. In Fig. 4 is shown how the conduit is brought intothe subway and showing it as running along the top of the wall and loweredge orthe arched roof of the subway, and I also show at 64 a branchconduit laid along the arch or the roof of the subway and in operativeconnection with the conduit 6, discharging its contents into thatconduit. There may be as many branch conduits as desired, those over ornear to the trains passing over track B and going in a direction toforce any pressure the motion of the train may make into mouth b andthose trains moving on track A forcing it into mouths turned in theopposite direction to mouth b.

The above construction described so far is intended for subways alreadyconstructed but where a new subway is in process of construction then mypreferred way of ventilating it is seen at 65 in Fig. 4, which consistsof simple conduits rising from the very apex of the roof of the subwaypreferably, passing preferably under ground to a kiosk and in operativeconnection with the conduit 6. This construction relieves the subwayfrom containing any part of the conduit. The conduit is hidden from viewand can be run any reasonable distance to a kiosk or to any otherstructure answering the purpose, and in this manner a subway may befully ventilated.

In Fig. 5 I show that the conduit 6 may be in form of an archcorresponding with the arch of the roof of the subway and may haveopenable doors 7 the upright part .of the conduit 6 being a part andportion of a kiosk or other appropriate structure, the kiosk not beingshown for want of room. The inven- IOC tion as shown in Fig. 4 may beused entire, if desired, or the conduits showninside the subway may beomitted, if desired'. The conduit 6 may take up the whole of the side ofa kisok or only a portion, if desired. By my arrangement of myVentilating apparatus nothingunsightlyis presented in the street,

such as open holes, chimneys, or'other structures that would not only beunsightly, but obstructions to: the streets. By use of that form of myinvention shown at 65 i-n Fig. 4 a number of the conduits 65 canI be runto the same kiosk and discharge through conduit 6 the same, wha-t Idesire tosecure by Letters Patent is- 1. The combination with a subwayand an of the Hight, and a transparent conduit leading from adjacent theroof of said subway upward along the end of said dropped portion, thencehorizontally beneath the roof thereof, and thence upward to and throughthe roof of the elevated portion.

2. The combination with a subway and an entrance thereto havin@P theusual ight of steps, of a transparent housing or kiosk for said entrancecomprising an elevated portion over the upper part of said flight ofsteps and a dropped portion over the lower part of the Hight, and atransparent conduit leading from adjacent the roof of said subway upwardalong the end of said dropped portion, thence horizontally beneath theroof thereof, and thence upward to and through the roof of the elevatedportion, said conduit having its inner wall formed of a series ofsections `hinged to swing transversely of the conduit to facilitatecleaning.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. entrance thereto havin@ theusualiiight of steps, of a transparent ousifng or kiosk for saidentrance comprising an elevated portion over the upper portion of said'ilifght of steps and a dropped portion over the lower portion l THEODORED.
